Rendez-Vous With French Cinema — the film fest currently playing at Lincoln Center, the IFC Center and BAM — has sparked a Hollywood-francophone collaboration. Director James Toback’s planning a French-language feature for acting icon Alain Delon and current Gallic hunk Romain Duris that would pair the multigenerational stars for the first time. The idea came to a head Friday night at the festival after Toback introduced Duris’ “Persécution” at BAM. “Romain’s never met Delon,” Toback explained, “which is like Leonardo DiCaprio never having met Warren Beatty.” Toback and Duris then spoke over the weekend to go over their plans to work together. Toback added he’ll write a second, gender-bending role for Duris — who starred in a remake of his ’70s Harvey Keitel flick “Fingers” — because the actor once told him he wants the challenge of playing a woman on-screen. “I said, ‘You mean a transvestite?’ and he said that no, he really wants a female role,” said Toback who’s in final post-production on highly anticipated Cannes doc “Seduced and Abandoned” featuring Alec Baldwin, Ryan Gosling, Roman Polanski and Martin Scorsese.
